Abstract (en)
[origin: EP2258977A2] In a side turn signal lamp, an LED light source (8) is mounted to a base end of a light guide lens (3). A distal end of the light guide lens (3) curves toward the rear of a vehicle and a functional light distribution portion (11) including light diffusion steps (10) is formed in a curved portion, so that light from the LED light source (8) is diffused toward a side of the vehicle. In a design light distribution portion (12) between the LED light source (8) and the functional light distribution portion (11), a linear optical step (14) is formed on a rear surface of the light guide lens (3) so as to extend in a longitudinal direction of the lens. A portion of light headed from the LED light source (8) toward the functional light distribution portion (11) is reflected by the optical step (14) in front of the vehicle and diffused around the groove portion (15).
